Classloader problem, "loader constraint violation"
Any ideas? A search says "don't put the wrong things in the base package",
but UploadFileWrapper isn't in any tapestry packages.

Then, i guess you can create a component with a Textfield AND an Upload
component.
But i don't think creating a component here is really worthy... You can
simply add a form component in your page, having the two components.

Not a literal label, each fileupload also takes in a textfield string, so
each file gets a name.

If you mean that you want to wrap the Upload component with a label, i
suggest you create a new Component in your components package, then agregate
a label and a upload component in this one.
To publish the label component parameters, you can use the publishParameters
attribute of @Parameter, this way developers will have access to the inner
label component parameters from your outer custom component.

The tapestry package is com.x.y.t5, with the component being in
com.x.y.t5.components. I have a list of upload files, each with a label, so
I figured I'd create a wrapper object with the label string and the upload
object.
